discussion
Remarks. The new species is somewhat similar to D. flavipes Duda, 1930, but can be separated from the latter by the gena broad, 0.3 – 0.4 times as deep as eye in profile; palpus yellow; surstylus nearly parallel-sided, round distally in lateral view. In D. flavipes, the gena is 0.25 times as deep as eye in profile; the palpus is largely black; and the surstylus is clavated in lateral view (Kanmiya 1971). The species is distributed to the North of Kamchatka and Island Karaginsky, host plant Leymus mollis (Nartshuk & Khruleva, 2010).
